Occlusal force detection device and occlusal force detection method thereof

Abstract

The invention discloses an occlusal force detection device and an occlusal force detection method thereof. The device analyzes the size of occlusal force of the masseter muscle by detecting gas pressure changes inside a rubber pneumatic bag. According to the detection method, occlusal force measurement can be achieved by detecting gas pressure changes inside the rubber pneumatic bag, the device is simple in structure, safe and sanitary, the measured air bag is soft and is particularly suitable for an old person with tooth loss, the occlusal of teeth and the gingiva can be measured at the same time, the comprehensive food masticatory ability of the old person can be reflected more visually, the trouble caused when comprehensive evaluation can be only achieved when other instruments are adopted for measuring the teeth and the gingiva separately is omitted, and a nurse can better take care of the old person conveniently.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a bite force detection device and a bite force detection method. Background technique [0002] The decline of occlusal system function is a common phenomenon in the elderly. During eating, some foods cannot be chewed and crunched. If you or your caregivers do not understand their chewing ability and eat food that exceeds the range of oral chewing hardness, it is easy to occur Dangerous situations such as choking and food stuck. Understanding the chewing ability of the elderly and eating foods with appropriate hardness can prevent such incidents from happening, so as to provide better care and care for the elderly. Existing patents related to bite force detection devices, such as the patents with publication numbers CN1066974A, CN103565447A, and CN105686838A, are resistance strain gauges, which use the resistance strain generated by the resistance strain gauge due to pressure to me...

Problems solved by technology

Existing patents related to bite force detection devices, such as the patents with publication numbers CN1066974A, CN103565447A, and CN105686838A, are resistance strain gauges, which use the resistance strain generated by the resistance strain gauge due to pressure to measure the bite force, but cannot detect the bite force. For example, the patents with publication numbers CN105496430A, CN104997569A, and CN105012039A are capacitive measuring instruments. The principle is that the capacitance changes with the pressure deformation of the insulating medium, but the dielectric property of the capacitor is affected by the temperature to a certain extent, which affects the accuracy of the measurement. ; As the patent of Publication No. CN103083107A calculates the change of the tooth surface gap when the teeth are occlusal, the method of constructing the three-dimensional model of the teeth, and then carries out the occlusal force analysis, and the detection method of directly analyzing the occlusal force of the masticatory muscles is multi-purpose electromyographic analysis, but its application Needle electrodes and electrical stimulation technology are used to understand the state of muscle function. During the detection process, it will cause some damage to the tested person, and it is not suitable for the detection of the bite force of the elderly.

Looking at the literature, it can be found that the current research direction tends to detect the force of the teeth. The main function is to assist denture restoration and orthodontics. The development direction is single. For the elderly with missing teeth and decreased occlusal function, the measurement results may not be as good. satisfactory

For people with missing teeth, the food will not only be ground by the tooth grinding surface during actual chewing, but the gums will also touch the food. Ignoring the above situation will cause detection errors
